I have a bunch of alleged 2700mAH NiMH batteries I purchased a while ago from a place I've dealt with many times before. In the past I've always been happy with the batteries from this place. They're inexpensive and worked very well.
This new batch, however, has been a huge disappointment. The coverings, which actually provide electrical insulation for the case, are extremely thin, brittle, and several of them have split or cracked, exposing the metal case of the battery and presenting the danger of shorting. Even worse, the capacities I'm seeing are not remotely close to the 2700mAH that's advertised. I know most batteries advertise "total capacity", some portion of which can never, in practice, be used. But with most of these batteries, according to my MH-C9000, I'm seeing capacities well under 2000mAH.
I just put a brand new set through the "break-in" charge cycle and the charger is telling me the capacity is about 1800mAH. I realize that may increase a bit over time, but that's the kind of numbers I'm seeing on most of them. I'm getting tired of changing batteries twice a day in my scanner.
Does anyone know of a battery that actually lives up to its capacity claims? I'm not saying a 2700mAH has to go to 2700, but 2300-2400 would be nice. This getting only two-thirds of the rated capacity is getting very old.
